Original scientific paper The paper deals with the stress state analysis of the cycloid disc by using numerical and experimental methods for the most critical case of the meshing-single meshing. Cycloid disc is the vital element of the cycloidal speed reducer- mechanical power transmission of the new generation with g…
Study of Aluminum nitride (AlN) thin film deposited on silicon wafer and glass substrates by DC magnetron sputtering technique at different power variation. The X-ray diffraction and Fourier transform infrared spectroscopy (FTIR) study revealed the formation of the AlN phase. The optical characteristics of films, such…
The rare and highly aggressive adult soft tissue sarcomas leiomyosarcoma (LMS) and undifferentiated pleomorphic sarcoma (UPS) contain complex genomes characterized by a multitude of rearrangements, amplifications, and deletions. Differential diagnosis remains a challenge. MicroRNA (miRNA) profiling was conducted on a…
AIMS: Acute lung injury (ALI) induced by excessive hyperoxia has been employed as a model of oxidative stress imitating acute respiratory distress syndrome. Under hyperoxic conditions, overloading quantities of reactive oxygen species (ROS) are generated in both lung epithelial and endothelial cells, leading to ALI. S…
Nanocrystalline (Average grain size ∼200 nm) bulk AA2124 alloy was produced through high energy ball milling of microcrystalline powder followed by spark plasma sintering (SPS) at 480 °C with a holding time of 10 min. The effect of initial particle and grain size on the microstructural evolution as well as on the rela…
The evolution of pressure drop, drainage rate, saturation, and efficiency of combined philic, and phobic oil mist filters in real‐time are examined. The experiments used four different filter configurations, with a combination of oleophobic and oleophilic fibrous filter media, and one oleophilic only reference. The ef…
The ability of many copper metalloenzymes to activate O2 and transfer it to organic substrates has motivated extensive attention in the literature. Investigations focusing on synthetic analogues have provided a detailed understanding of the structures of potential intermediates, thereby helping to guide mechanistic st…
Nano-graphite/Fe3O4 composite (NG/FC) synthesized through deposition–precipitation method, was developed for the removal of methyl violet (MV) from aqueous solution. The parameters including pH, temperature and shaking time on MV removal efficiency were extensively investigated. The adsorption of MV increased smoothly…
Abstract Cu 2 ZnSnS 4 (CZTS)‐based materials have a useful band gap and a high absorption coefficient; however, their power conversion efficiency is low compared with that of CdTe and Cu(In,Ga)Se 2 ‐based solar cells. Two of the factors that strongly affect CZTS solar cell characteristics are the MoS 2 layer and the p…
Smart garments for monitoring physiological and biomechanical signals of the human body are key sensors for personalized healthcare. However, they typically require bulky battery packs or have to be plugged into an electric plug in order to operate. Thus, a smart shirt that can extract energy from human body motions t…
Al doped ZnO thin films were synthesized by ultrasonic spray pyrolysis technique. The concentration ratio of [Al]/[Zn] was varied from 1 to 5 %mol in the starting solution, in order to investigate the effect of doping ratio on the structural optical and electrical films properties. The films thicknesse was found in th…
MnO2-doped lead free 0.5[Ba(Zr0.2Ti0.8)O3]-0.5[(Ba0.7Ca0.3)TiO3] ceramics were synthesized by a high-energy ball milling process. We studied the phase formation process along different steps of the mechanical milling. We show that the addition of a small amount of MnO2 (x < 0.5 mol.%) improves the dielectric and ferro…
Results of broadband dielectric/electric investigations of (Na0.5Pb0.5)(Mn0.5Nb0.5)O3 ceramics are presented in wide frequency range 20 Hz–3 GHz. The electric properties of (Na0.5Pb0.5)(Mn0.5Nb0.5)O3 ceramics are mainly governed by high ionic conductivity. One ionic and three polaronic contributions to electrical cond…
(Ba0.92−xCa0.08Ndx)(Ti0.82Zr0.18)O3 (0 ≤ x ≤ 0.02) were prepared through solid reaction route. The relaxor behavior of (Ba0.92-xCa0.08Ndx)(Ti0.82Zr0.18)O3 have been studied. When x = 0, a broad dielectric peak with frequency dispersion occurred, with increasing Nd3+ content, the relaxation and diffuseness degree was s…
Lead-free piezoelectric barium titanate (BaTiO3 or BT) ceramics with various grain sizes were prepared by hot isostatic pressing (HIP) and post-annealing. The dielectric, ferroelectric and electromechanical properties were investigated. The average grain sizes of the ceramics were controlled by changing the post-annea…
Polymer thin films find wide range of technological applications such as coatings, adhesives, lithography, sensors and as solid state electrochemical cells they can be directly deposited on to chips in any shape or size. In the present work pure and doped (KNO3 & MgCl2) polyvinyl alcohol thin films were synthesized us…
The effect of lanthanum addition to γ-alumina supported bimetallic carbides has been studied for the reaction of dry methane reforming using four different lanthanum loading levels of 1, 5, 10 and 15 wt% of lanthanum. It has been demonstrated that the addition of lanthanum to supported bimetallic carbides at low loadi…
The X-ray powder diffraction (XRPD) pattern of [Mn(NH3)6](ClO4)2 at room temperature can be indexed in the regular (cubic) system (Fm $$ \overline{3} $$ m space group) with lattice cell parameter a = 11.5729 Å and with four molecules per unit cell. The XRPD pattern at 100 K is evidently different, and it indicates low…
Photon harvesting by reducing reflection loss is the basis of photovoltaic devices. Here, we show the efficacy of Al-doped ZnO (AZO) overlayer on ion beam-synthesized nanofaceted silicon for suppressing reflection loss. In particular, we demonstrate thickness-dependent tunable antireflection (AR) from conformally grow…
A mathematical model for semibatch pH‐shift reactive crystallization of l ‐glutamic acid is developed that takes into account the effects of protonation and deprotonation in the species balance of glutamic acid, crystal size distribution, polymorphic crystallization, and nonideal solution properties. The crystallizati…
